Definitions

  • a separate retaining centralizer and rotating mechanism require plenty of room and are heavy. Numerous operational means make the operation and structure complicated and slow.
  • a supporting fork 11 is pivotably mounted within the supporting sleeve and provided with cylindrical end plates 12 and arms 13 positioned therebetween.
  • the distance between the arms 13 of the fork corresponds to the thickness of the pair of jaws so that the jaws are slideable between the arms.
  • the arms are intended to keep the jaws pressed against each other.
  • the drill rod When drilling a rock, the drill rod extends through the hole 2 of the frame.
  • the supporting sleeve is rotated to such a position with respect to the jaws that the gaps of the jaws are in alignment in a manner shown in FIG. 12, the jaws are out of engagement with the drill rod.
  • the drill rod is thus able to rotate freely within the opening device.
  • the required torque by means of which the jaws are displaced to the fastening position and the drill rod starts to rotate with the opening device, is obtained by a desired tightening of the friction plates.
